well I went to the marina yesterday to run a few tests and pull the carbs and something else went wrong. I checked for spark on all 12 wires and all was good. ran a compression check and all cylinders had 120 psi. while checking for spark it was idling a little high then it started shifting/banging into gear on its own without touching the controls. did this a few times then it stopped but I couldn't make it go into gear with the controls. it also stopped pumping water so my beast guess is something happened to the lower unit. I'm going to get it back home this weekend and pull the lower unit.
